Wadsworth Mansion (also known as Wadsworth Family Mansion) was an early-1970s American rock band from Providence, Rhode Island. Its members were Steve Jablecki (guitar, keyboards, vocals), Wayne Gagnon (guitar, vocals), Russ Sevigny (a/k/a Russ Dana, original drummer) Mike Jablecki (drums] and John Poole (bass guitar). The group took its name from Wadsworth Mansion at Long Hill in Connecticut.
In November 1970, Wadsworth Mansion released their first single, a non-album version of "Sweet Mary", backed by another non-album track, "What’s On Tonight". "Sweet Mary" would prove to be the band’s only hit song peaking at #7 on the US Billboard Hot 100 singles chart for the week ending 27 February 1971.
In April 1971, Wadsworth Mansion issued their first and only album on the heels of their first single’s success, the self-titled Wadsworth Mansion. In support of the album, the group released their second single in April 1971 with the tracks, "Michigan Harry Slaughter" and "Havin’ Such A Good Time", but the single failed to make Billboard’s Hot 100 singles chart.
In July 1971, Wadsworth Mansion issued their third and final single with the non-album track, "Nine On The Line", backed by "Queenie Dew". The release would also fail to enter Billboard’s Hot 100 singles chart sealing Wadsworth Mansion’s fate as a one-hit wonder.
In January 1972 Forrest Howie McDonald replaced Wayne Gagnon on guitar. The band recorded 4 new songs at the CBS studios in New York City. The songs recorder were Dont Ask Me, Over and Over, Dusty Angel, and Why Does it Hurt so Bad. Produced by James Calvert and Norman Mariano. In May of 1972 Charlie Flannery replaced Mike Jablecki on drums. The band pulled out of RI June 21 1972 just ahead of Hurricane Agnes. After playing the night of June 23 at the Colonels Garter the Susquehanna River flooded and the club was underwater. This was the lineup of the band until after their last tour of the south in August of 1982 when the group officially disbanded. Forrest and Steve reformed the band in Hollywood the following summer and changed the name to Slingshot at the producers urging.
